Description

The technical field to which the invention relates

This application relates to wireless communications.

State of the art

An improved uplink mechanism has been introduced for Third Generation Partnership Project (3GPP) standards. As part of the enhanced uplink mechanism and enhanced Layer 2 (L2), new functional entities have been introduced into medium access control (MAC), including enhanced MAC-e / es entities. In a wireless transmit / receive unit (WTRU), enhanced MAC-e / es are considered as a single sublayer. However, on the network side, the enhanced MAC-e / es and the enhanced MAC-es can be considered separate, with the improved MAC-es resident in the Node-B and the improved MAC-es resident in the serving radio network controller (SRNC). One entity with enhanced MAC-e and one entity with enhanced MAC-es are present for each WTRU in Node-B and in SRNC, respectively. Objects are separate on the network, so that Node-B can be given more critical real-time functionalities of the enhanced MAC-e.

1 is a block diagram of an enhanced MAC entity 100 for a WTRU. The enhanced MAC in the WTRU includes a hybrid automatic repeat request (HARQ) module, a transmission sequence number setting (TSN) and multiplexing module, an enhanced uplink transport format combination (E-TFC) selection module, and two segmentation modules.

The HARQ module performs MAC functions related to the HARQ protocol, which contains the storage of the payloads of the improved MAC-e and their retransmission. The HARQ module determines the E-TFC, the retransmission sequence number (RSN), and the power offset to be used by level 1 (L1).

The multiplexing module and TSN connects multiple protocol data units (PDUs) with the enhanced MAC-es PDUs and multiplexes one or multiple enhanced MAC-es PDUs into a single enhanced MAC-PDU, which must be transmitted in a subsequent transmission time interval (TTI) at the command of the module E-TFC selection.

The E-TFC selection module performs E-TFC selection in accordance with scheduling information, relative and absolute grants received from the UMTS Terrestrial Radio Access Network (UTRAN) via L1 signaling, and the provision of service, which is signaled via RRC to resolve a conflict between different streams displayed on the E-DCH.

The segmentation module performs the segmentation of the MAC-d PDU.

Figures 2 and 2A show an object with an improved MAC-e and an object with an improved MAC-es located in the Node-B and RNC, respectively. With reference to FIG. 2, an enhanced MAC-es sublayer controls certain E-DCH functionality. An object with improved MAC-es contains a disassembly module, a reorder and a sequence distributor, a reorder / merge module and a reassembly module.

The reorder distribution module sends the enhanced MAC-es PDUs to the corresponding priority queue buffer based on the configuration of the serving radio network controller (SRNC) and based on the identity of the logical channels.

The queuing / combining unit changes the order of the received enhanced MAC-es PDUs in accordance with the received TSN and Node-B marking (i.e., CFN, subframe number). Enhanced MAC-es PDUs with subsequent TSNs, upon receipt, are delivered to the disassembly module.

The macro-diversity selection module works in enhanced MAC-es in the case of software transmission using multiple Node-Bs.

The disassembly module is responsible for disassembling the MAC-es PDUs, including removing the enhanced MAC-es header.

The reassembly function reassembles the segmented MAC-d PDUs and delivers the MAC-d PDUs to the corresponding object with MAC-d.

On figa shows an object with MAC-e associated with the planning module E-DCH. The enhanced MAC-e object comprises an E-DCH control module, a demultiplexing module, and a HARQ object.

The E-DCH scheduling module controls the allocation of E-DCH cell resources between the WTRUs. Based on planning requests, planning grants are defined and transferred.

The E-DCH control module is responsible for receiving scheduling requests and transmitting scheduling grants.

The demultiplexing module demultiplexes the PDUs with MAC-e into PDUs with enhanced MAC-es. Enhanced MAC-es PDUs are routed to the SRNC in the associated MAC-d stream.

The HARQ module can support multiple HARQ processes. Each process is responsible for creating ACK or NACK messages indicating the receive status during E-DCH transmission.

FIG. 3 shows the states of a serving radio resource controller (RRC) for a 3GPP compliant WTRU with improved uplink. A WTRU may operate in several states, which depend on the activity of the user. The following states were defined: Idle, CeILDCH, Cell_FACH, URA_PCH, and Cell_RCCH. RRC state changes are controlled by a network using RNC parameters, and the WTRU itself does not decide on state changes.

In the Cell_DCH state, the assigned physical channel is allocated to the WTRU in the uplink and downlink channel. The WTRU is known at the cell level according to their current active setting. The WTRU may use dedicated transport channels, shared transport channels, or a combination of these transport channels.

The WTRU is in the Cell_FACH state if it is assigned to use common control channels (e.g., CPCH). In the Cell_FACH state, no physical channel is allocated to the WTRU and the WTRU continuously monitors the FACH direct access channel (eg, S-CCPCH) or the high-speed sharing channel (HS-DSCH) in the downlink channel. The default WTRU is assigned to a shared or shared uplink transport channel (eg, RACH), which can be used at any time according to the access procedure for that transport channel. The position of the WTRU is known for the UTRAN at the cell level according to the cell in which the WTRU last performed the cell update.

In the Cell_PCH state, no dedicated physical channel is allocated to the WTRU. The WTRU selects the RSN and uses continuous reception to monitor the selected RSN through the corresponding PICH. No uplink activity is possible. The position of the WTRU is known for the UTRAN at the cell level according to the cell in which the WTRU last performed a cell update in the CELL_FACH state.

In the URA_PCH state, no dedicated channel is assigned to the WTRU. The WTRU selects the RSN and uses continuous reception to monitor the selected RSN through the corresponding PICH. No uplink activity is possible. The location of the WTRU is known at the level of the UTRAN registration area in accordance with the URA assigned to the WTRU during the last update of the URA in the Cell_FACH state.

As part of the enhanced uplink mechanism, an enhanced random access channel (E-RACH) has been introduced for the CELL_FACH state. The E-RACH refers to the use of an Enhanced Dedicated Channel (E-DCH) in the Cell_FACH state or the resource / physical channel used by the WTRU for associative uplink access. Previously, the only uplink mechanism for WTRUs in the Cell_FACH state was RACH transmission using the Aloha split approach with a receive indication message.

With the introduction of the E-DCH in the Cell_FACH state, the WTRU and the network may require the introduction of enhanced MAC-e / es to allow communication between the WTRU and the network. Due to the nature of the operation of the E-DCH in the Cell_FACH state, many problems with E-DCH MAC resources may occur. One problem relates to determining how and when to install objects with enhanced MAC-e / es. In addition, rules are desirable regarding the location of entities with enhanced MAC-e / es and whether enhanced MACs and / or enhanced MAC-es are shared or dedicated objects. In addition, additional signaling between the RNC and the Node-B interface (Iub) for setting up and managing MAC entities is desirable. Accordingly, methods for managing E-DCH resources and managing TSN numbering are desirable.

SUMMARY OF THE INVENTION

Disclosed are methods and apparatus for controlling improved MAC-e and resources with improved MAC-es and the corresponding variables for E-DCH in enhanced Cell_FACH state. Due to the nature of the E-DCH in the uplink (UL) in the Cell_FACH state and the fact that the WTRU can set and release the E-DCH more often, methods for managing TSN numbering are described.

Detailed description

As mentioned above, the term “wireless transmit / receive unit (WTRU)” includes, in particular, user equipment (UE), a mobile station, a fixed or mobile subscriber unit, a pager, a mobile phone, a personal wireless minicomputer (PDA), a computer or any other type of user device capable of operating in a wireless environment. As mentioned hereinafter, the term "base station" includes, in particular, Node-B, a site controller, access point (AP) or any other type of interface device capable of operating in a wireless environment.

FIG. 4 shows a wireless communication system 400 comprising a plurality of WTRU 410, Node-B 420, CRNC 430, SRNC 440, and a core network 450. As shown in FIG. 4, the WTRU 410 is connected to a Node B 420 that is connected to the CRNC 430 and SRNC 440. Although three WTRU 410, one Node-B 420, one CRNC 430, and one SRNC 440 are shown in FIG. 4, it should be noted that any combination of wired and wireless devices can be included in the wireless communication system 400.

Turning to the foregoing, CRNC 430 and SRNC 440 may collectively be referred to as UTRAN.

FIG. 5 shows a functional block diagram 500 of a WTRU 410 and a Node-B 420 of the wireless communication system 400 shown in FIG. 4. As shown in FIG. 5, the WTRU 410 is connected to the Node B 420 and both are configured to implement a method for managing and setting resources with improved MAC-e / es in the Cell_FACH state.

In addition to the components that can be found in a typical WTRU, the WTRU 410 includes a processor 415, a receiver 416, a transmitter 417, and an antenna 418. The processor 415 is configured to implement a method for managing and setting resources with improved MAC-e / es in the Cell_FACH state. A receiver 416 and a transmitter 417 are coupled to a processor 415. An antenna 418 is coupled to both a receiver 416 and a transmitter 417 to facilitate transmission and reception of wireless data.

In addition to the components that can be found in a typical base station, the Node-B 420 includes a processor 425, a receiver 426, a transmitter 427, and an antenna 428. The processor 425 is configured to implement a method for controlling and setting resources with improved MAC-e / es in Cell_FACH state. Receiver 426 and transmitter 427 communicate with processor 425. Antenna 428 communicates with both receiver 426 and transmitter 427 to facilitate the transmission and reception of wireless data.

The WTRU 410 may be configured to transmit over the E-RACH to register the WTRU 410 in the network for an initial RRC connection request, a cell request, and a re-request. Connection requests are transmitted through a common control channel (CCCH). When the WTRU is registered, the WTRU can transmit dedicated traffic channel (DTCH) or dedicated control channel (DCCH) traffic to the network. In a network, a DTCH is a bi-directional channel that transmits user data, and DCCH traffic contains dedicated control information between the WTRU and UTRAN. It is established through the RRC (Radio Resource Management) connection setup procedure. However, when the WTRU 410 transmits an initial E-RACH access attempt, entities with enhanced MAC-e and entities with enhanced MAC-es may or may not be installed. Accordingly, hereinafter, several configuration alternatives of the enhanced MAC-e and the enhanced MAC-es are described in more detail below.

Returning to FIG. 4, the WTRU 410 can be performed using the enhanced MAC-e / es object 419 when both the WTRU 410 and the network support E-RACH (i.e., the ability to use E-DCH in CELL_FACH state) and HS- DSCH. Here, the HS-DSCH is a downlink transport channel shared by several WTRUs. The HS-DSCH communicates with one dedicated physical downlink channel (DPCH) and one or more high-speed shared control channels (HS-SCCH). Object 419 with enhanced MAC-e / es in the WTRU 410 may include a HARQ module, a multiplexing module and TSN, an E-TFC selection module, segmentation modules, a module used to attach an E-RNTI, and a module used to calculate CRC for channel traffic General Management (СССН). The CCCH supports the general procedures required to establish a dedicated link to the UTRAN. The CCCH may comprise a RACH and an E-RACH, a direct access channel (FACH) and a paging channel (PCH). An enhanced MAC-e / es entity 419 may also comprise an access class management module. WTRU 410 may transition to the Cell_FACH state when uplink data exists for transmission or when it is already in the Cell_DCH state and the network moves it to the Cell_FACH state due to a lack of activity, etc. WTRU 410 may be configured to maintain an entity with enhanced MAC-e / es while it is able to transmit uplink data on an E-DCH. The WTRU 410 may further be configured to maintain an entity with improved MAC-e / es when operating in idle mode when an RRC connection establishment request is initiated by the WTRU 410.

Node B 420 can be configured to use x objects with MAC-e (from enhanced MAC-ei to enhanced MAC-ex), where x is the number of shared E-DCH resources for all types of traffic. Each object with enhanced MAC-e may contain an E-DCH scheduling module, an E-DCH control module, a demultiplexing module, and a HARQ module. Objects with enhanced MAC-e can also be configured to read the E-RNTI used to resolve conflicts. Objects with enhanced MAC-e can be configured to communicate with WTRUs that are not assigned a U-RNTI or E-RNTI when the WTRUs will communicate via CCCH. Each object with enhanced MAC-e can be associated with a shared E-DCH resource that the WTRU receives as part of a random access procedure. For example, the Node-B 420 may be configured to use an object with improved MAC-e while the WTRU attempts to access the E-RACH, and / or after the WTRU has performed cell selection / reselection (i.e., traffic DTCH / DCCH). Objects with enhanced MAC-e can be preconfigured in Node-B 420 (that is, installation when the E-DCH resource pool for CELL_FACH state and idle mode is provided to Node-B), or installation can be done in response to a signal received from WTRU or RNC. Alternatively, the Node-B 420 may be configured to install and maintain one dedicated entity with improved MAC-e for each WTRU while the WTRU is in a predetermined state.

CRNC 430 can be performed using objects with enhanced MAC-es (from enhanced MAC-esi to enhanced MAC-esy) used only for CCCH traffic, where y is the number of E-DCH shared resources in the cell. Each object with enhanced MAC-es is associated with a set of E-DCH shared resources that can be used by the WTRU. Each object with enhanced MAC-es can contain a disassembly module, a queue changing and queuing distribution module, a queuing changing module, a macro-diversity selection module, a reassembly module and a correction module for errors detected by CRC. Each object with enhanced MAC-es can be used during communication with a WTRU that has not been assigned a U-RNTI or E-RNTI (i.e. for CCCH traffic). CCCH traffic can be terminated at CRNC 430 such that CCCH data traffic is not routed to SRNC 440. Alternatively, CRNC 430 can be configured to set up one dedicated MAC-es dedicated entity for each WTRU while the WTRU is in this state.

The SRNC 440 is implemented using z entities with enhanced MAC-es (from enhanced MAC-esi to enhanced MAC-esz) for DTCH / DCCH traffic, in which z is the number of WTRUs in the Cell_FACH state. Each of z objects with enhanced MAC-es can be associated with the WTRU 410 after its WTRU-id is determined. Each object with enhanced MAC-es can contain a disassembly module, a queue change and queue distribution module, a queue change module, a macro-diversity selection module, and a reassembly module. The SRNC 440 may be configured to set up an object with enhanced MAC-es in response to the introduction of the WTRU in the Cell_FACH state. DTCH / DCCH traffic ends at SRNC 440.

Alternatively, the Node-B 420 and CRNC 430 may be configured to maintain one entity with improved MAC-e and MAC-es, respectively, for each WTRU while the WTRU is in the Cell_FACH state, regardless of E-DCH resources.

Alternatively, the Node-B 420 and CRNC 430 can be configured to set up objects with improved MAC-e and improved MAC-es after the Node-B 420 assigns and transmits an E-DCH Radio Network Temporary Identifier (E-RNTI) for the WTRU 410.

In some scenarios, the SRNC 440 may not know the identification of the WTRU 410 before the first transmission of the WTRU 410, which occurs after the reception of an Receive Indicator Channel (AICH) or E-AICH. In this case, the SRNC 440 may be configured to install enhanced MAC-es for the WTRU 410 at a time when the WTRU is read from the header. Accordingly, a new Iub signaling procedure may be required to instruct the SRNC 440 to set up an enhanced MAC-es entity for this WTRU.

When shared resources with enhanced MAC-e and / or enhanced MAC-es are setup for a given connection, they can be set up as part of the general transport channel setup procedure between the RNC and Node-B 420.

FIG. 6 shows a flowchart where a CRNC 430 pre-configures and stores a common object with enhanced MAC-es, and Node-B 420 pre-configures and stores a common object with enhanced MAC-e for each set of improved allocated resources a channel (E-DCH) that can be assigned to a WTRU according to an E-RACH access procedure. With reference to FIG. 6, a CRNC determines an E-DCH resource set and signals to a Node-B (610). CRNC and Node-B pre-configure and store common objects with enhanced MAC-es and enhanced MAC-e, respectively, for each available set of (620) E-DCH resources. The WTRU performs a random access procedure and obtains a set (630) of E-DCH resources. An RRC connection request message is received from the WTRU in Idle Mode using the E-DCH set received using random access procedure (640). The Node-B distributes the E-RNTI, and the enhanced MAC-es entity is an SRNC setting for the WTRU (650).

Since the enhanced MAC-e for CRNC and the objects with the improved MAC-e of Node-B are pre-configured for the E-DCH resource set, the improved MAC-e and the enhanced MAC-es for the CCCH can be configured to work as common objects that simultaneously associated with one WTRU (i.e., for a WTRU that has accepted access to the E-RACH). In one embodiment, shared entities with enhanced MAC-e and MAC-es can only be used for initial WTRU traffic. Alternatively, enhanced MAC entities may be used during a time when the WTRU is communicating through an E-DCH resource set corresponding to this enhanced MAC entity. Then, an RRC connection setup completion message may be received indicating that the WTRU is in connection mode (660).

An entity with enhanced MAC-es in the CRNC may be associated with a set of E-DCH shares used by the WTRU 410, or a shared E-RNTI that is selected by the WTRU 410. The SRNC 440 may be configured to set up a dedicated entity with enhanced MAC-es for each WTRU operating in the Cell_FACH state that is registered and has an E-RNTI allocated to it, and the entity may be maintained in this state for at least the duration of the WTRU in the Cell_FACH / CELL_PCH state for DTCH / DCCH traffic. For DTCH / DCCH traffic, data is first received at the shared entity with enhanced MAC-e associated with the E-DCH shared resource used by the UE, and then sent to the dedicated entity with enhanced MAC-es in the SRNC via the Iub / Iur interface. Accordingly, when the enhanced MAC-e is a common entity for any WTRU using a set of resources, the process of determining the WTRU by the Iub / Iur frame protocol may be desirable. Hereinafter, several alternatives are described in more detail.

In a first alternative, the Node-B 420 may be configured to transmit data over a common transport channel (for WTRUs using E-DCHs in the Cell_FACH state) using an Iub stream. Since the Iub is a shared stream, the CRNC 430 may receive data from this shared stream through the WTRU and not know which WTRU this data belongs to. Therefore, the Node-B 420 can be configured to transmit the WTRU identifier (WTRU-ID) in the Iub frame header when the enhanced MAC-e communicates with a particular WTRU in the Cell_FACH state (i.e., for DTCH / DCCH traffic). Similarly, CRNC 430 may be configured to transmit the WTRU identifier in the Iur frame header. The WTRU may contain an E-RNTI when transmitted through the Iub interface, or S-RNTI when transmitted through the Iur interface. This should allow the SRNC 440 to know the proper address to forward data to the correct dedicated object with enhanced MAC-es for the WTRU.

In another alternative, the WTRU may comprise one or a combination of E-RNTI, U-RNTI, or C-RNTI, or S-RNTI. For CCCH traffic, no WTRU is present and thus the Iub frame protocol should not contain an E-RNTI. The CRNC 430 may be configured to detect that the traffic belongs to the CCCH traffic from the logical channel identifier, and direct the correct entity data with enhanced MAC-es to the CRNC 430, which is associated with the proper E-DCH resource. In a further embodiment, one common transport channel for DTCH / DCCH traffic and one transport channel setting for each set of E-DCH resources for CCCH traffic are possible. The Node-B 420 may be configured to receive CCCH traffic and send data to a transport channel associated with an improved MAC-e entity in which data was received.

In another alternative, when both the Node-B 420 and the CRNC 430 are configured to share common objects with enhanced MAC-e and enhanced MAC-es, the WTRU 410 may be configured to transmit the WTRU identifier in the PDU header with enhanced MAC-es . The Node-B 420 may be further configured with a disassembly module capable of decoding the enhanced MAC-es PDU header and determining a WTRU identifier. By transmitting information to PDAs with enhanced MAC-es, the Node-B 420 should not transmit an Iub frame with WTRU identifier information. For example, the WTRU 410 may be configured to transmit the WTRU identifier in the enhanced MAC-es header only during initial transmissions in order to resolve conflicts. In this case, the Node-B 420 can be executed with an object with improved MAC-e, which uses the initial transmission to determine the sending procedures for serial data in subsequent transmissions to the RNC. The WTRU 410 may transmit the WTRU identifier until it accepts the absolute grant of the E-DCH, at which point the WTRU 410 may stop transmitting the WTRU identifier.

In another alternative, the Node-B 420 may be configured to receive the WTRU from the WTRU and retrieve the WTRU from the first transmission. The Node-B 420 may then store the WTRU identifier and use this information to transmit the WTRU identifier to the SRNC 440 or CRNC 430 using Iub signaling during subsequent transmissions. When the WTRU 410 releases the E-DCH resource set, the Node-B 420 may be configured to erase the WTRU identifier. Alternatively, if a subsequent attempt to access the E-RACH occurs and another WTRU is decoded, the Node-B 420 may modify the stored WTRU information to reflect the new WTRU.

In yet another alternative, after the Node-B 420 receives the first transmission from the WTRU, the Node-B 420 can use the first transmission to determine which WTRU the data belongs to. Once the WTRU identifier is determined, the Node-B 420 can establish a semi-dedicated stream to the RNC for the duration of the WTRU connection with the E-DCH resources. This creates a stream through a temporary connection between the common enhanced MAC-e and the dedicated enhanced MAC-es. This may be a setup performed by transmitting an Iub signal notifying the RNC of the need to initiate a flow setup between the common enhanced MAC-e and the enhanced MAC-es entities corresponding to the WTRU. In this case, the WTRU should not be indicated in the Iub frame protocol, because the WTRU is present in the header of the enhanced MAC e of each transmission, and information is sent to the RNC via the Iub frame protocol.

Alternatively, since E-DCH resources can be negotiated between the Node-B 420 and the WTRU without involving an RNC, E-DCH-related functionality, such as enhanced MAC-es, can be transferred to the Node-B 420. For this embodiment, the flows logical channel can be established between objects with improved MAC-es and objects management radio link (RLC). Alternatively, the WTRU 410 and the Node-B 420 can establish a common transport channel and the WTRU and linearization channel (LCH) -ID can be transmitted over the Iub and / or Iur frame protocol.

Although features and elements are described above in specific combinations, each feature or element can be used alone, without other features and elements, or in various combinations with other features and elements or without other features and elements. The methods or flowcharts presented here may be implemented in a computer program, software, or firmware located on a computer-readable storage medium for execution by a universal computer or processor. Examples of computer-readable storage media include read only memory (ROM), random access memory (RAM), a register, cache memory, semiconductor storage devices, magnetic media such as internal hard drives and removable drives, magneto-optical media and optical media such as CD-ROM discs; and digital versatile discs (DVDs).

Suitable processors include, for example, a universal processor, a dedicated target processor, a conventional processor, a digital signal processor (DSP), a plurality of microprocessors, one or more microprocessors associated with a DSP core, a controller, a microcontroller, user-programmable integrated circuits (ASICs) gate arrays (FPGAs), any other type of integrated circuit (IC) and / or state machine.

The processor, together with the software, can be used to implement a radio frequency transceiver for use in a wireless transmit / receive unit (WTRU), user equipment (UE), terminal, base station, radio network controller (RNC), or any host computer. WTRU can be used together with modules implemented in hardware and / or software, such as a camera, camcorder module, videophone, speakerphone, vibration device, loudspeaker, microphone, television transceiver, hands-free telephone headset, keyboard, Bluetooth ^® module, frequency-modulated radio block (FM), liquid crystal display (LCD), organic light-emitting diode display (OLED), digital audio player, universal player, player module for computer games, Internet -browser and / or module of any wireless local area network (WLAN) or ultra-wideband (UWB) network.
